The future?

Papped in a supermarket so not the best quality ever from my phone camera. There is a massive new Morrison's store that has opened in Wrexham in the last few weeks so I decided to nip in there on the way home. It was actually quite different in feel with a huge open plan area as you go in and the bakers/deli etc in almost seperate shops around the edge of this area, it was quite nice.
What caught my eye though was these water sprayers keeping the herbs moist. Maybe a little uneccessary!
